Transforming a Cold Space into a Radiant Retreat

The goal for this master bathroom renovation, spearheaded by the skilled professionals at Kraftmaster Renovations, was to introduce an element of pure, consistent luxury. As with many high-end remodels, the selection of tile, marble, and stone provides stunning aesthetics, but these materials are notoriously cold underfoot, especially in New Jersey's colder months. The homeowners wanted a reliable heating solution that could cover the entire 135 sq. ft. floor space and seamlessly integrate into their sophisticated design.
WarmlyYours provided a custom electric floor heating plan utilizing the flexible TempZone™ Floor Heating Cable embedded within a Prodeso uncoupling membrane. This method was ideal for the large, rectangular room, allowing for complete coverage with a tight 3.75'' cable spacing to ensure an even, consistent heat output. The system is controlled by the intuitive nSpire Touch Thermostat, giving the homeowner precise, programmable control over their comfort schedule. The radiant heat not only eliminated the shock of cold floors but also acts as an effective supplemental heat source, contributing to the overall comfort and energy efficiency of the master suite. The outcome is a truly luxurious master bath that provides a warm welcome every time.
